wood fiber insulation boards (also called soft fiber insulation boards) are manufactured from debarked wood waste. This is ground into fine wood fibers, briefly heated and then pressed into sheets. Serve as an adhesive, the wood's resin, so no further additions required. As a protection against decay and fire protection Vebesserung but ammonium sulfate is added. To the roof insulation wood fiber insulation boards be treated. This is done either with natural resins or bitumen. The latter is not as ecologically meaningful classification.
properties of wood fiber insulation boards
The wood fiber insulation achieves a thermal conductivity of 0.040 to 0.055 W / m² K. Thus, it has a good insulating property. In addition, the wood fiber insulation boards have good sound insulation effect and a high heat storage capacity and have moisture-regulating effect. Wood fiber insulation boards are in the fire protection class B2 - classified - normal flammability. wood fiber insulation boards are offered in different thicknesses as a rigid, pressure-duty insulation and as a flexible insulation panels.
application
wood fiber insulation boards can be used in the intermediate rafters or roof insulation. Furthermore, the wall insulation in drywall and insulation and sound insulation of ceiling . Meanwhile it also dry bar insulation systems are available with wood fiber insulation boards. In general, the wood fiber insulation boards in a circumferential tongue and groove, so that no gaps. Wood fiber panels can be easily edited.
